which the following is a specification.

This invention relates to a preparation forstopping and preventing leaksin; radiators, Water pipes, boilers and other liquid holding vessels, orcontainers. ject of the invention is to prevent Water escaping fromleaks already formed, it can be, as in the case of radiators, placed inthe Water before any leak is detected, and will automatically preventany leak from showing up by stopping any puncture as soon as itbecomesof sufficient size to permit Water to enter it.

In testing the device l have found that considerable care is required toget just the right amount of some of the ingredients, as the proportionsemployed are as important as the ingredients themselves. 1 v

In preparing ten gallons of liquid composition I take one pound ofasbestos, one and-one half poundsiof dry paper, two gallons of Wheat orrice paste, one half ounce of gum arabic, one half ounce of Englishrosin, one half ounce of safrol, or any similar deodorizing agency, onefourth ounce of salicyclic acid and one eighth of a pint of denatured orWood alcohol. This last is employed as a solvent, especially for theresin.

With the exception of the safrol, alcohol, and paste these ingredientsare in a dry and finely comminuted state. To the abovel add a sufficientamount of Water to make up the ten gallons.

Inan automobile radiator for example about one quart of the solution isadded to the Water already contained in the radiator, which Will bepossibly from four to five gallons.

As previously stated the proportions of some of the ingredients are veryimportant. If more than the amount of paper is used it will clog, ifless is used it will failto do the work required of it. binder for thepaper and asbestos, and the amount used is important. It must be justsuficient to allow the ingredients to remain in a fluid state until theyhave entered the opening to be stopped, and to cause them to becomehard, dry and impervious tc Water as soon as exposed to the outer air.The proportions mentioned are those that exhaustive tests have proven tobe most et i cient, and in preparing the solution accurate measurementsshould be made.

W'hatl claim is;

A composition for stopping leaks in radiators, boilers, etc., consistingot finely ground paper, "one and one half pounds, comminuted asbestos,one pound, two gallons of a starchy paste, one hall" ounce oi gumaraloic or an equivalent gum, one half ounce resin, a suitabledeodorizer, one halt ounce salicylic acid, and one eighth of a pint oralcohol, all added to a sufi'icient amount of Water to equal tengallons.
